Efficient Management of Peach trees to promote High yield

Peach trees are easy to grow, affect the light, cause withered branches and empty chamber, and result in outward movement, resulting in premature senescence, low flowering and fruit setting rate, and serious reduction of yield and quality, so we must pay attention to scientific planting management measures. First, scientific pruning of peach trees is very important, the time is divided into winter pruning: there are natural open heart type, two main branch open heart type and oblique palm leaf fan shape, etc., while summer pruning is mainly to pick the heart and control the overgrowth. The wound should be smeared with healing film in time to facilitate healing as soon as possible and prevent glue flow and other diseases. Second, effective measures to promote fruit 1. Some peach trees with little pollen are poor in self-pollination, so other varieties of peach trees should be used as pollination trees. Some varieties mixed with more than two can be cross-pollinated to improve the seed setting rate. For varieties without pollen or with a small amount of pollen, artificial pollination should be carried out or bee pollination should be released to improve the fruit setting rate. 2. Controlling shoots and promoting flowers and fruits: peach trees are easy to flow gum and strip, which seriously affect the growth of fruit. The Huawang No. 1 ring ligation technique can be used to control glue disease and control striping, so as to transform the growth function of peach trees into reproductive function and improve the fruit setting rate of peach trees. Third, flower and fruit thinning and fruit thinning in time for varieties with high self-flowering and seed-setting rate, the earlier the better; for varieties without pollen or low self-flowering seed-setting rate, no flower thinning but fruit thinning. Fruit thinning should be finished within 2 weeks after anthesis, and the fruit on the high-quality fruit-bearing branch with a length of 5m / m and a thickness of 0.3m / 0.5cm should be selected as far as possible. There were 3 fruits in each long fruit branch, 2 fruit in the middle fruit branch and 2 fruit in the short fruit branch, and one fruit in each long fruit branch, and the fruit spacing was kept between 15m and 20cm. 4. the principle of fertilization in orchards requires that the fertilizers used should not adversely affect the orchard environment and fruit varieties, but should be registered or exempted from registration by agricultural administrative departments. Formula fertilization and balanced fertilization are advocated according to the nutrition analysis of soil and leaves. ① base fertilizer: applied after fruit harvest in autumn, mainly organic fertilizer, such as compost, stable manure, ring manure, manure, green manure, straw, weeds and so on, mixed with a small amount of nitrogen fertilizer. The amount of base fertilizer generally accounts for 70% of the total amount of fertilizer applied to fruit trees in the whole year. ② topdressing: in the early stage of fruit development of young trees and fruit trees, nitrogen and phosphorus fertilizer was the main topdressing, and phosphorus and potassium fertilizer was the main fertilizer in the later stage of fruit development. The last topdressing was carried out 30 days before the fruit harvest. During this period, in addition to spraying foliar fertilizer, Zhuangguotieling was sprayed once before flowering, young fruit stage and fruit expansion stage, which can thicken the peach stalk and fruit stalk, prevent flower and fruit falling, and improve the fruit expansion speed. 5. The new bright spot of bagging technology is to spray the fruit surface with new high fat film in the young fruit stage, and then spray it appropriately with the fruit expansion speed, which is similar to the fruit bag, which can significantly improve the fruit surface finish, increase color, reduce diseases and insect pests and pesticide residues, and produce pollution-free fruit. Sixth, smear to protect the tree general to prevent and cure the gum, rot, canker 1, prevent and cure the gum disease of the fruit tree: remove the gum stain in the glue stain, smear the lotion, and the cationic active elements infiltrate into the tree, which can destroy the pectin synthesis in the tree, inhibit the gum pollution and hydrolyze the gum molecules quickly, and completely cure all kinds of fruit tree gum disease. 2. Prevention and treatment of rot and canker: gently scratch the diseased skin with a blade (vibration can make the spores fly), smear this lotion with a brush, the diseased skin begins to dry up after 3 days, and the diseased skin infected with dead spores begins to fall off after 30 days.
